Red Hat OpenStack Services on OpenShift (formerly Red Hat OpenStack Platform)
- Following a fresh deployment of RHOSP 17.1.2 with ovs-dpdk, during workload testing, VNF vms under load testing (pushing traffic to PMD threads) are crashing and causing openvswitch restart on the ovs-dpdk hypervisor.
- We see ovs-vswitchd coredumping in /var/log/messages:
